I have the Needone 48L heat/cool. I like it, and it keep things rock solid for me I store at 66* and 65%. I have converted to all drawers instead of shelves.
Here are a few things to consider.
1st- You not come close to the estimated storage capacity unless you convert to all drawers instead of shelves. This can be expensive as the drawers run about $40 each, It will likely cost more for the convert then the actual unit. If your handy and can find Spanish ceder locally then it's easy to make your own.
2nd- Unless you insist on keeping your collection at 70* don't bother with the heating unit, you can save some money there. That said I keep my home cold, usually around 65* year around so that was why I got the combo.
3rd- If you think you will see your collection inside the unit, you won't. the glass is too dark and the light inside is useless.
I now find it to be just another box of cigars. A box that takes up more space than my stack of tubberdors which hold way more cigars and were purchased after the needone to start storing overflow that will happen. I do not regret buying it, I still use it, and I keep it filled, but in hindsight, I would have just purchased a few more containers and spent the rest on more cigars.
